XM7 plays fddseek.wav, relay_on.wav and relayoff.wav from its data
directory (linux-sdl/sdl/api_snd2.cpp:155-159, 213-267). The three come
from Win32/ of the XM7 V3.4L77SX+z09 final release archive by PI. and
Ryu Takegami, archived on archive.org as xm7tr_3477sxz09.
fmtownsmx.zip holds the two members geartowns reads, each matching MAME
fmtowns.cpp:2941,2947 (CRC f3fc636e, 16e78766). Music.xml is Supermodel
0.4's (trzy/Supermodel efbdc86, git blob 0d87602a), the copy the pack
ships where a platform's package leaves it out.
sfiii2a.zip for FBNeo, the Odin board sets, HyperScan, Basilisk II,
the XM7 and FM-7/X1/PC-88/VideoBrain MiSTer ROMs, the FM Towns ROMs
RetroBat now checks, CD-i vmpega.rom, Apple II card ROMs for POM2, four
Amiga accelerator ROMs, and the no$gba DSi SD image (release asset).
Each file matches a hash its profile or platform declares, or MAME's.
6ee162f8 imported MAME device and machine archives that each carried the ROMs of every slot option reachable from the set (H19 terminal ROMs in sys68k_cpu30.zip, 371 ISA card ROMs in slvrball.zip). MAME reads a slot card from the card's own archive, so those members were never read there.
Each archive is rebuilt as TorrentZip from the recipe its profiles declare (their union when profiles of several MAME versions differ), every member checked by crc32 and sha1. A copy whose recipe build already exists under the same name is removed, keeping the one filed under its manufacturer. 341-0057.bin, held only in these copies, stays in the MAME 0.220 a2pic recipe under .variants/. Every member removed is still held elsewhere in the collection.
Built from individual ROMs (FMT_SYS, FMT_DOS, FMT_FNT,
FMT_F20, FMT_DIC, MYTOWNS, MAR_EX0-3) using the tsugaru
structured container format (12-byte name + length + data).
